A bottle has 5.50 pints of milk. Express the decimal as a fraction. a. 5 $\frac{1}{2}$ b. 5 $\frac{50}{100}$ c. $\frac{550}{100}$ d. $\frac{550}{1000}$

Solution:

5.50
[Original decimal number.]

= 5 50 / 100
[As there are two digits after decimal point, write the decimal as a fraction with denominator 100.]

= 5 50÷50 / 100÷50
[Divide the numerator and denominator by their GCF, 50.]

= 5 1 / 2
[Simpify.]

So, the equivalent fraction of the decimal number 5.50 is 5 1 / 2.

Sunny cut 2.4 inches long color paper to paste it on one side of a cube. Express the decimal as a fraction. a. $2\frac{3}{5}$ b. 3$\frac{2}{5}$ c. 2$\frac{2}{5}$ d. 2$\frac{1}{3}$

Solution:

2.4
[Original decimal number.]

= 2 4 / 10
[As there is one digit after decimal point, write 0.4 as a fraction with denominator 10.]

= 2 4 ÷ 210 ÷ 2
[Divide the numerator and denominator by their GCF, 2.]

= 22 / 5
[Simplify.]

So, the equivalent fraction of the decimal number 2.4 is 22 / 5.

Nathan wants to buy a leather flask worth $47.95. Write the price of the a leather flask as a fraction. a.$$48\frac{1}{6}$ b. $$47\frac{21}{22}$ c.$$47\frac{19}{20}$ d. None of the above

Solution:

47.95 = 4795100
[Express decimal as a mixed number.]

= 4795÷5100÷5
[Divide 95 and 100 by their GCF 5.]

= 471920

The price of the a leather flask is $4719 / 20. Correct answer : (3) 124. Jerald had $\frac{6}{7}$ of a apple. Write the decimal form for the fraction of the apple. a. 0.98 b. 0.857 c. 0.88 d. None of the above Solution: 67 = 0.857 [Divide numerator with denominator.] The decimal form for the fraction of apple is 0.857 Correct answer : (2) 125. Holly had 1 lb of cornflakes. She gave 0.45 lb of it to her friend Kelsey. Express the quantity of cornflakes Holly gave to Kelsey as a fraction. a. $\frac{9}{22}$ b. $\frac{1}{2}$ c. $\frac{10}{21}$ d. $\frac{9}{20}$ Solution: 0.45 = 45100 [Convert the decimal number to a fraction.] = 45÷5100÷5 [Divide the numerator and the denominator by their GCF, 5.] = 920 [Simplify.] Holly gave 9 / 20 lb of cornflakes to Kelsey. Correct answer : (4) 126. Dennis bought stamps for$32.60. Express the cost of the stamps as an equivalent fraction. a. $$32\frac{6}{100}$ b.$$32\frac{60}{100}$ c. $32$\frac{3}{50}$ d.$$32\frac{3}{5}$

Solution:

32.60 = 3260100
[Convert the decimal part to fraction.]

= 32(60÷20)(100÷20)
[Divide the fraction by 20, the GCF of 60 and 100.]

= 3235
[Simplify.]

The equivalent fraction for the cost of the stamps is \$323 / 5.
